you cannot do it like this, the x system use driver and use the hardware 
how it want after using the driver,
but what you can do is:
writing a windows driver for the guest that will emulate a 3d video card 
and then writing a device for qemu
that will exploit some of the host 3d graphics video card gpu for this 
emulated card,
but this really is not simple at all
